1 Claim.

This invention relates to a window construction and particularly to the sliding-swinging type of window and is related to our Patent Number 2,375,546, issued May 8, 1945.

An object of the invention is the provision of weather stripping which is novel and peculiarly adaptable to the sliding-swinging sash type window.

Another object is to provide a different and novel type of weather stripping which has unusual and differing qualities for application to both the upper and lower sashes.

Another object is to provide a means whereby when the sashes are in closed position they will be held rigidl against horizontal movement.

A further object is the provision of a releasing and lock means which will definitely lock the lower sash in closed position thus locking both sashes from inward movementfrom the outside.

With these and other objects in view, which will appear hereinafter, the invention consists of the novel construction, combination and arrangement of parts, more specifically referred to and illustrated in the accompanying drawings, in which Figure 1 is a vertical section of the window construction,

Figure 2 is a horizontal sectional view taken on the line 22 of Figure 1, and

Figure 3 is a detailed'section of the window showing the releasing and locking mechanism for the lower sash.

Referring to the drawings, the numerals l and I l indicate the side members of the window frame having the upper cross member I2 and lower sill [3. The upper sash I4 is hinged at l5 for inward swingable movement and on the opposite or free side of the sash is arranged a fiat spring I6 positioned against the side ll of the frame, as indicated at IT. Thi spring is bent at l8 at right angles so as to seat against the corner of the s free side of the sash and at its end has the bent back portion [9 to frictionally take up any play between the sash and vertical outer stop 20.

The spring l6 extends substantially for the length of the upper sash and such weather protective means is not required of the hinged side of the sash because that'side'is flush. against the window frame and the leaf hinge acts as a weather strip on the hinge side.

On the inward side of the sash is another spring member 25 which is a combinedstop and weather frame H, as indicatedat 26 and has the turned back portion 21 to hold the sash firmly against the end portion I9 of the spring It. In order that the upper sash may be swung inwardly, the stop 25 extends slightly short of the bottom of the upper sash.

The lower sash is hinged at 3| and has provided, adjacent its free side, a flat spring member 32 with a curved portion 33 at its outer end, the spring being held against the side II, as in-, dicated at 34. The same retaining means holds a weather strip element 35 which is held flush against the side of the sash and this strip, in conjunction with the stop 36, will effectively weather strip the lower sash.

In dotted lines is shown the movement of the Weather strip 35 which is limited in its inward movement by the resilient stop 36 after the sash I has been swung inwardly. The stop 36 is fastened at 31 in a recessed portion of the side I l. The stop 36 is formed to fit into a groove 38 formed in the lower sash 30, the stop and groove fitting closely and cooperating to act as weather strip and stop air flow.

The spring 32, the strip 35 and stop 36 extend substantially for the length of the lower sash.

Referring particularly to Figure 3, a releasing and locking means is illustrated which will defi nately prevent horizontal movement of the lower sash while the lower sash, in turn, will hold the upper sash against horizontal movement when the strip. The lower edge of the upper sash and .the

upper edgeof the lower sash are formed with conventional complementary tapered sealing latter is in a lower position. The releasing means comprises a movable stop 39 disposed in a countersunk housing 39' pivoted at 40 with a recess 4|, the lower end of which will rest against the pin 42 carried by the housing 39"when the stop 39 is moved outwardl from the recess 43, to its looking position, by grasping the finger lift 44.

Due to the space occupied by the spring 32 and strip 35, at the free side of the sash 30, the stop 39 will not interfere with the opening movement of the sash.

The above is the preferred embodiment of our invention, but it is to be understood that modifications may be resorted to which fall within the scope of the claimed invention. The hinges l5 and 3|, extending for the length of the upper and lower sashes respectively, are of th type which when in the proper position will permit vertical movement of the sashes.

What we claim is: In a window frame having a sash mounted for 3 vertical sliding and horizontal swinging movestrips (not shown). This stop is held against'the ment, said sash formed with a rabbeted edge on the inner side thereof 0PP9il iron; the 5 thereon, said rabbeted edge formed with an inwardly opening depression along the length thereof, a metal strip secured to said frame and formed with a resilient detent adapted for engagement in said depression for weather stripping the inner edge of said sashin the sliding position in said frame, and another spring device comprising a pair of co-extensive elongated fiat resilient members disposed inconfronting position, imeans securing said members along one longitudinal edge to said frame in confronting position to a vertical edge of the sash thereof, the inner of said mem bers engaging bowed portion engageable by the outer member, the second member normally being defiected away from said bowed portion and engageable withthe adjacent vertical edge of the sash to provide a weather seal.
